" To all it may concern:

Be it known that I, FRANK H. ADAMS, a

- citizen of the United States, residing at able the machine tonutomatically stop itself k a disk phonogra h lnnchineeqnipped' with whenthe playing of a record has been coin plctedf The invention consists in the 'con- ,structionand combination of parts herein- :ffter' described and shown in the drawing, and definitely pointed out in the appended claims.

In the drawing Figure 1 is a plan view of the invention. ig. 2 is afront elevation of so much of seid machine as is necessary to show said invention. Fig-31s a bottom View of the track arm and connections. Fig.- 4 .is a side elevation thereof. Fig. 5 is a, perspective view showing the track arm ifter, and a part of the track arm and its adjuncts adjacent to said lifter. Fig. 6 is encnd view otthe turned down end of slide 12.

Referring to'theperts by reference characters, 1 represents-the sound box; 2 the sound box arm; and 3 the swinging tone arm, the seine-beings taper tube which is itself pivoted on a vertical axis 3*. The sound box arm is pivoted to the free end of the tepertube on a horizontal axis indicated by -2.- i represents the turn table, and 5 a disk record, which does not diner ifrorn' the ordinarily used disk records, except that I it has one ormore grooves 5'- formed-in its up er 'surfacennd extending from' the inner en ofthe laying gr'odvefi" spirally toward vertica nxisfl adjacent to the edge" of theturn; table. 7 represents the needle, carried track bar.

of which there may be more than one, if desired. The resent invention is adjunctive to a .disk p onograph.having ,the above 65 mentioned pnrts.

10 represents the track bar which is pivot' ed to a bracket 11 fixed to the frame of the machine at one side of the turn 'table,--the pivoting axis 11 being substantially at right angles to the axis 2 about which the sound box tube turns. From its supporting pivot this bracket arni extends over the turn table toward the axis thereof "est in front of the sound box and the nee leucerried thereby-- The rear edge of this track is curved more or -less accurately about a center which is coincident with the axis 3 upon whichthe taper tube turns.

"On the underside one arm 10 is anexto tenfion piece '12 which is in the form of a slide mounted and supported in gliides 1'0.

The end ofthis slide progects] beyond the i end of the track bar, and normally rests upon the smooth top surface of the disk'like has 18 of the track bar lifter 13.

A clamp 14, which is secured to the tube 2 adjacent the sound box, is provided at its outer or front end with a, downwardly ex-- tending arm 15 carrying at its lower end a friction roller 15" for engagement with said The shape and disposition iofthe arm 14 is such that the miller 15 wil'lfibe over the track bar, but will not engage therewith when the track bar is in the horizontal B5 position it will occupy when its ext ension member 12 is resting its shown (men the disk '13. Under these conditions and with the parts constructed and arranged as stated, the ordinary operetionof the phonograph flo in laying the record willnot bechenged. t he track bar lifter 13 has in its bottom a hole which fits friction tight on impart of the spindle 4 which projects up t'hf'ough the record. The part oi saiii iifte'r which ,95 extends shove the 'base 13 ispreferablyjin' theflormpf an inverted trnncfiicd cone, wh'ose axis is coincident with the axis bit-the.

turntable. In the outer surface of this cone is n, spiral groove 13* which extends from t the base 13 to the top thereof. 'g The sliding extension-member 12 his near .xifs free enflgggahonlder 1 2, whichflies in the.

putt; needle]? needile n gres is rather quicklyfow ard the axis of the turn toward the center of the turn table about the axis 3.'. There is also a shoulder 12 carried b thefslide 12 adjacent the outer edge of t e disk record 5, and also projectingeinto the path of the needle as the taper tu' swings-about its axis 3 away from the axis of the turn table.

The operation ofthedevice thus scribed will be as follows":

As stated, the parts are normally in 'the position shown by the full lines in F i '2, -when a disk record is being played. on .Ethe needle 7 comes to the end of the playing groove, it will enter one of the grooves in the disk record, and thereby Wlll be carried far detable; and during this movement the needle will engage the shoulder 12 with suilicient force to movethe slide 12- inward so as to move the inner end of said slide into the spiral groove 13" of the track bar lifter.

Then, as the lifter 'continues to revolve in unison-with--the turntable, the said spiral ove will graduall carr the end. ofsaid s ide"12"upward*an there y the track bar will be lifted until it finally assumes the position shown b dotted linesin F ig. 2. As this track bar is ifted, it comes into contact with the friction wheel 15, and thereby the sound box is swung up about its axis 2, lifting the needle clear of the record. The inclination of the track bar upon which the sound box is now supported will be such, as shown by dotted linesin Fig. 2,'that gravity will cause the sound box to roll down this track bar toward the outer edge of the disk,

- causing, of course, the-taper tube 3 to swing laterally about its axis. As the soundbox so travels, the" needle 7 will be carried into contact with the shoulder 12., and thereby the slide 12 will be moved outward. In so movinggit will'I'be-drawn free and clear of 4 I the fter 13, and therefore, the track bar will drop to its former horizontal position. When it does so drop, thesound box will be allowed to swing down, and ,theneedle 7 will enter one'ofthe playing grooves. "Thereafter the playing of the record will proceed in the usual way. It will, of course, be understood that it is desirable, that the shoulder 12 shall occupy 'a position such that when the needle 7 strikes and moves it, and when, as a result, the track bar drops, the needle will take its place in the playing groove of the record at "or.very near the beginning thereof.

If disk records were always of'one size, say 12 inches in diameter, and, if the playing groovesalways began and'c'nded at the same definite distance from the axis, the two shoulders 12 and 12 could be immovable relative to the slide, and could be accurately placed "thereon. As a matter'of-fact,'however, there are two standard sizes of phono- Jgraph disks, to wit, twelve inch and ten inch. Likewise there is some variation in movablyfixed to the slide, and are so constructed that by their movement they may present shoulders for the-needle to engage with, at various distances from the axis of the disk. v

One of thesedevices is a lever 17, which is pivoted to the under side of the slide 12, its end which is farthest from the pivot 11, be ing provided with a lu'r'ality of steps or shoulders 17. This liver may be turned uponits pivot so as to bring into the path of.

the needle that one of the shoulders which will be enga ed by the needle at the desired point, viz. t e point at which the track bar will drop so as to allow the needle to enter the playing groove of the disk at the desired point. Since this lever is carried by the slide, the striking of the end of the lever b the needle will move the slide outward wit the same results as when theneedle struck the shoulder 12*.

Means for holding the lever 17 in any adjusted position may be provided. In fact,

a simple segment latch is shown in the face for engagement in these grooves. The

metal of which the lever 17 isformed has extending in a general direction outward thcrefrom,that is away from the axis of the-disk. It may be provided with plural shoulders 19, 19", so placed that this lever may be turned on its pivot to brin either of these shoulders into the path of t e needle,

If, for citsmple, the playing groove on the disk stops at a greater distance than common from the center of rotation, it is dcsirableto swing this lever 19 .so as to bring one or the other of the shoulders 19, 19? into the path of the needle. When the needle in its movement' toward the center of the disk" strikes whichever shoulder is in its path, it will move the'slidc 12 inward, and cause its end to enter the spiral groove ofthe lifter, with the results which have been beforeexplained.

amaze It may be desirable to provide means by which the end of the slide 12, when it has once entered the spiral groove 13", Shhll be compelled to stay in said groove until the 7 move emerges from the top of the lifter. his may not be essential, and obviously is not essential to the invention in its broader aspects, but, as stated, it may be desirable. To that end the lower or lifting surface of the spiral grooveis undercut, and the (pro jecting end of the slide 12 has it turned down flange or too 12, which enters the undercut part of said spiral groove. -Th1s construction may perhaps best be produced b winding a strip of'metal 13 sp rally, as s own, around a central arbor 13, and connecting it at the top and bottom to said arbor. In that event, there should beat the top of the lifter an inwardly projecting surface 13, and the front edge of said down turned finger should be beveled as shown in Fig. 6. VVhen the beveled edge of the fing er comes in Contact with said surface 13' it will be lifted above the level of the top of the spiral groove; and there will also provided another projection 13" which will en gzige said finger when in this position, and push it off of the top of the lifter. This will insure that even i'tthe needle shall not strike the shoulder 19) or one of the othershonldam; in its path carried by the slide with suflicient force to move the slide outward, nevertheless the slide will be pushed back and oil of the lifter so that the tracknrni will certainly fall to the horizontal position and allow the needle to enter the playing groove, Before the slide is pushed off the lifter in the manner just stated, the sound box and needle will have been restored to starting position.

The wuy in which to stop the rotation of the turntable ina disk phonograph machine is to s'wing'the automatic brake lever '6' outWard,--that is, away from the turn table. Ordinarily this is done by hand, but

the mechanism which has been heretofore described may be utiliiicd to produce that result. For example, the lever 1? 1s swu ig on. its ,pivot so that it projects slightly untier-the forwardly-projecting part of the i' pt'fir 6 when the track arm is elevatedlor inclined in themunner previously described, Jjthfitportion of lever 17=whichfis beneath "the "forwardly projecting part of lever 6 will engage thelatter, moving'the seine sl ghtly away irom the turntable so that the s ring the'hrake device may throw the opposite. end qf the lever 6 or the brake shoe into enfntwith the periphery of the turn- "fie, nd stop the'rotation of the lotis to he understood that any device ear edby the'soignddiok'mny be utilizedfor aging shoulder on the slide 1 2 to fitsiinovdmont; and that the util zawardly toward the center of t 'e arm comprising a device havin lower gaged by a part movable with the sound t-ion of the needle for this purpose is merely a matter ofipreferenoe. l

The word phonograph as used in the s ecifioation and claim is not intended to limit the invention to a machine sold under the name, phonograph, but includes any sound reproducing or so-cal'led talking machine utilizing a disk record, of the general type herein shown and described.
